Train a 2 year old dog?

its possible no matter the age thats is very generous of you to do i would say teach her like if she were a puppy shes a pitbull they are independent dogs it would be easier if you talked to a person who has a ptbull too and ask him or her on ideas of how to train her. when you see her trying to eat the others dogs food try to get the bowl away from her and say no dont let her eat his bowl let murphy eat his part of the food while nikki is on the leash being hold by you keep reapeating this show her where her bowl is and dont let her near his bowl. their os great books in pet smart or petco that help you how to teach you the basic commands get her a long leash i forgot what its called that way she cant escape i hope she goes to a good home:)
